How to Use the Merriam-Webster MCP in Google ADK

Instantiate an McpToolset with your server URL and add it to your LlmAgent. Your agent can then call defineword or getthesaurus as needed.

Q: Can Google ADK agents filter Merriam-Webster tool access?

Yes, you can use a tool name filter in your McpToolset configuration. This limits which functions your agent can see, keeping your toolset clean.

Direct dictionary lookups for Google ADK

Your agent uses `define_word` to pull exact definitions from the official source. This adds a layer of precision to your Google Cloud-based automation tasks. It works by connecting the tool directly to your agent's toolset. Your process gains immediate access to verified linguistic data.

Thesaurus integration for enterprise agents

Call `get_thesaurus` to let your agent choose the most accurate vocabulary for your specific document needs. It retrieves synonyms and antonyms that match standard usage. This fits into your existing Google ADK workflow. It keeps your agent's language aligned with professional standards.

Structured semantic data for agents

The server provides structured responses that your agent can parse for downstream logic. It helps your agent make better decisions based on word meanings. This MCP Server provides the data backbone your agent needs. It works regardless of your underlying model size or complexity.

Setup guide

Set up Merriam-Webster MCP in Google ADK

Prerequisites

Python 3.10+ installed
google-adk package (pip install google-adk)
Active Vinkius subscription with a valid endpoint token

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Merriam-Webster tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Merriam-Webster_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Merriam-Webster tools via MCP.",
    tools=mcp_tools,
)
